PURPOSE: To increase inductance and to prevent the generation of an electromagnetic field radiant radio, by a method wherein thermocouples or compensating conductors, which are always paired, are formed in a solenoid or a helical coil, and the coil is covered with a material having a high permeability.
CONSTITUTION: Compensating conductors 4a and 4b, which are always paired, are formed in a solenoid or a helical coil, and the pair is held in a flexible tubular shield 4c, made of, for example, a stainless or other slender pipe having a thin thickness, so that they are insulated from each other. Additionally, the shield 4 is caused to process an insulating capacity being durable to a voltage which an object to be measured has. The inside of the flexible tubular shield 4 is filled with an insulating material, made of, for example, a polyethylene or other mold-form material mixed with an oxidized iron powder as an insulating material. The above refers to the compensating conductor, and the same can be stated on a thermocouple as well.
